Hole in the Wall!

Classical Mechanics Level 4

A large tank is filled with water (density \(\rho\)). A small hole is made at a depth of \(h = 10m\) below the water surface. The range of water issuing out of the hole is \(R\) on ground. What Extra Pressure (in atm) must be applied on the water surface so that the range becomes \(2R\)?

Details and Assumptions:

\(\bullet\) The answer to this problem is an Integer
\(\bullet \rho = 10^3 kg/m^3\)
\(\bullet g = 10 m/s^2\)
\(\bullet\) Water is assumed to be ideal liquid
